Temperature Setpoint Adjustment/Occupancy
Override
The large dial on the face of the network sensor
functions in two ways: to increase or decrease the
setpoint temperature, and to change the controller
mode from unoccupied and occupied. When the dial
is rotated slightly, the backlight on the LCD lights up. If
the dial is rotated slightly again, and the controller is in
the unoccupied mode, the controller changes from the
after-normal-working-hours setback mode to the
normal-working-hours comfort mode. To adjust the
setpoint, continue rotating the dial until the current
setpoint is displayed and flashing. Turn the dial
clockwise to increase the setpoint and
counterclockwise to decrease the setpoint. Stop turning
the dial once the desired setpoint is reached. The new
setpoint stops flashing and becomes fixed after a few
seconds.
°F/°C Temperature Mode Selection
Certain models include a °F/°C push button on the face
of the network sensor to provide temperature scale
options for display. Pressing the push button toggles
the temperature mode between Fahrenheit and Celsius
on the LCD.
Temperature/RH Mode Selection
Temperature/RH models include a push button on the
face of the network sensor to allow occupants to view
the temperature and relative humidity of the zone.
Pressing the push button toggles between temperature
and RH on the LCD. The LCD defaults to temperature
5 seconds after the push button is released.
The NS-AHR710x-0 and NS-APR710x-0 models also
have the capability to set the desired default display to
either temperature or RH. Follow this procedure to
change the default display on these models:
1. If the display backlight is off, press and release the
push button to illuminate the backlight. If the
display backlight is already on, proceed to Step 2.
2. Press and hold the push button for 5 seconds to
switch to the desired default display (either
temperature or RH).
Note: The desired default display will flash for
5 seconds. After the display stops flashing, the new
default display is in effect.

3. Release the push button; the desired display is
now the new default display.
Fan Mode Selection
Some models include a fan mode push button on the
face of the network sensor to select the desired fan
speed. Pressing the push button toggles the fan speed
between AUTO-OFF-low-medium-high on the LCD.
Network Sensor Addressing
Most network sensors have a default device address of
199 on the SA Bus. For averaging models, the sensor
address must be set on the dual-switch DIP switch
block on the network sensor Printed Wire Board
(PWB).
Averaging models are shipped with both switches set
to ON, resulting in a device address of 203. Device
addresses can be DIP switch set from 200 to 203; see
Figure 4 and Table 1 for more details.
